--The shape of an engagement ring that fits into your everyday life

The roots of engagement rings can be traced back to ancient Rome. At that time, rings were made of iron and gold and were used as a sign symbolizing an eternal promise. As time passed, diamonds began to be placed at the center of the ring, and the image of it as a "symbol of eternal love" became stronger. Modern engagement rings are typically designed with a large diamond set in the center, known as a "prong setting." Its classical and glamorous appearance is perfect for a special day. However, since it is such an important ring, wouldn't it be nice if it could be worn naturally in everyday life? With this idea in mind, CHIKAKO YAJIMA proposes bridal rings that fit into "modern life."

The ring in the photo is a diamond ring from the popular " Protrude" series. Unlike typical prong settings, this design features diamonds set at an angle. The angle allows the diamonds to capture light in a three-dimensional way, giving them a subtle yet impressive presence. The contrast with the matte gold is beautiful, and it blends in with simple fashion, so it naturally blends into everyday outfits. In addition, it can be stacked perfectly with the "Infinity" ring from the bridal line, and when the two are stacked together, a sophisticated balance is achieved. The top and bottom fit together perfectly, making it comfortable to wear. Stack the wedding ring and engagement ring to create one beautiful shape. One of the charms of this series is that you can enjoy it in such a casual way.

— A New Kind of Engagement Ring for Everyday Life
Bridal jewelry from Japan, crafted for modern lifestyles.

The tradition of engagement rings dates back to ancient Rome. Early rings were made of iron or gold and symbolized a promise of eternity. Over time, diamonds became the centerpiece, and engagement rings grew to represent eternal love.
Today, the classic prong-set diamond ring remains a timeless symbol—elegant and perfect for special occasions.

But for something so meaningful, why not wear it every day?
At CHIKAKO YAJIMA, a Japanese jewelry brand inspired by form and structure, we propose bridal rings that harmonize with your daily life.

Featured here is the Protrude ring from our signature collection.
Rather than a traditional prong setting, this ring features a diamond tilted at a unique angle. This handcrafted setting allows the stone to catch light from various directions, creating a soft yet captivating brilliance. Paired with a matte gold band, it brings together refinement and simplicity—making it ideal for both casual and formal wear.

This ring is also designed to pair seamlessly with our Infinity ring, part of our bridal line. When stacked, the two rings interlock in perfect harmony, both visually and in fit—resulting in a beautiful, balanced design that's easy to wear every day.
